On August 26th, The Night Of The Fireworks Display, We, Who Had Always Had A One-sided Love For Each Other, Got Together And Devoured Each Other's Bodies As If We Had Been "in Love" With Each Other For More Than Ten Years.

Ayaka and Kenichi had been close since childhood. Ayaka stayed in their hometown, while Kenichi moved to Tokyo for a job. Reuniting for the first time since their coming-of-age ceremony, the two felt a sense of nostalgia and became aware of each other. This was because, as they entered adolescence, they had begun to see each other as members of the opposite sex... However, not wanting to ruin their friendship, they grew up without confessing their feelings of 'like,' and before they knew it, they had grown distant. The time they spend together after so long. The fireworks festival that stirs their emotions. What will be the outcome for these two, who had a 'mutual unrequited love'?
